| Basis of Presentation [Abstract] | |
| Basis of Presentation | Basis of Presentation and Summary of Operations Employers Holdings, Inc. (EHI) is a Nevada holding company. Through its wholly owned insurance subsidiaries, Employers Insurance Company of Nevada (EICN), Employers Compensation Insurance Company (ECIC), Employers Preferred Insurance Company (EPIC), and Employers Assurance Company (EAC), EHI is engaged in the commercial property and casualty insurance industry, specializing in workers' compensation products and services. Unless otherwise indicated, all references to the “Company” refer to EHI, together with its subsidiaries. The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X of the Securities Exchange Act of 1934, as amended. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal, recurring adjustments) necessary for a fair presentation of the Company’s consolidated financial position and results of operations for the periods presented have been included. The results of operations for an interim period are not necessarily indicative of the results for an entire year. These financial statements have been prepared consistent with the accounting policies described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012. The Company considers an operating segment to be any component of its business whose operating results are regularly reviewed by the Company’s chief operating decision makers to make decisions about resources to be allocated to the segment and assess its performance based on discrete financial information. Currently, the Company has one operating segment, workers’ compensation insurance and related services. Use of Estimates The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities, at the date of the consolidated financial statements, as well as the reported amounts of revenues and expenses during the reporting period. As a result, actual results could differ from these estimates. The most significant areas that require management judgment are the estimate of unpaid losses and loss adjustment expenses (LAE), evaluation of reinsurance recoverables, recognition of premium revenue, deferred income taxes, valuation of investments, and the valuation of goodwill and intangible assets. Reclassifications Certain prior period information has been reclassified to conform to the current period presentation. |

| Accounting Changes and Error Corrections [Abstract] | |
| Accounting Changes and Error Corrections | Changes in Estimates During the third quarter of 2013, the Company reduced its estimated reserves ceded under the Loss Portfolio Transfer Agreement (LPT Agreement) by $14.5 million. This change in estimate resulted in a $10.1 million cumulative adjustment to the deferred reinsurance gain–LPT Agreement (Deferred Gain), which was also recognized in losses and LAE in the consolidated statement of comprehensive income, so that the Deferred Gain reflects the balance that would have existed had the revised reserves been recognized at the inception of the LPT Agreement (LPT Reserve Adjustment). This change in estimate was the result of the determination in the third quarter of 2013 that an adjustment was necessary to reflect observed favorable paid loss trends. This change in estimate increased net income by $10.1 million, or $0.32 per basic and diluted share, for the three months ended September 30, 2013 and $0.33 and $0.32 per basic and diluted share, respectively, for the nine months ended September 30, 2013. During the third quarter of 2013, the Company reallocated $24.3 million in reserves from non-taxable periods prior to January 1, 2000 to taxable years, which reduced our effective tax rate by 10.5 percentage points for the nine months ended September 30, 2013. This change in estimate was the result of the determination in the third quarter of 2013 that a reallocation of reserves among accident years was appropriate to address a continuation of observed loss trends. The income tax impact of this change in estimate increased net income by $5.0 million, or $0.16 per basic and diluted share for the three and nine months ended September 30, 2013. |

| New Accounting Standards [Abstract] | |
| New Accounting Standards | New Accounting Standards In February 2013, the Financial Accounting Standards Board issued Accounting Standards Update Number 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income (Topic 220). This update requires companies to report the effect of significant reclassifications out of accumulated other comprehensive income on the respective line items in net income if the amount being reclassified is required under GAAP to be reclassified in its entirety to net income. For other amounts that are not required under GAAP to be reclassified in their entirety to net income in the same reporting period, an entity is required to cross-reference other disclosures required under GAAP that provide additional detail about those amounts. This update became effective prospectively for reporting periods beginning after December 15, 2012. The Company adopted this update beginning in the first quarter of 2013. The adoption of this new guidance did not have a material impact on the Company's consolidated financial condition or results of operations. |

| Fair Value of Financial Instruments | Fair Value of Financial Instruments The carrying value and the estimated fair value of the Company’s financial instruments were as follows:
The Company's estimates of fair value for financial liabilities are based on a combination of the variable interest rates for the Company's existing line of credit and other notes with similar durations to discount the projection of future payments on notes payable, and have been determined to be Level 2 fair value measurements, as defined below. Assets and liabilities recorded at fair value on the consolidated balance sheets are categorized based upon the levels of judgment associated with the inputs used to measure their fair value. Level inputs are defined as follows:
The following methods and assumptions were used to determine the fair value of each class of assets and liabilities recorded at fair value in the consolidated balance sheets. Fair value of available-for-sale fixed maturity and equity securities is based on quoted market prices, where available, and is obtained primarily from third party pricing services, which generally use Level 1 or Level 2 inputs. The Company obtains a quoted price for each security from third party pricing services. The quoted prices are derived through recently reported trades for identical or similar securities. For securities not actively traded, the third party pricing services may use quoted market prices of similar instruments or discounted cash flow analyses, incorporating inputs that are currently observable in the markets for similar securities. Inputs that are often used in the valuation methodologies include, but are not limited to, broker quotes, benchmark yields, credit spreads, default rates, and prepayment speeds. The Company also performs a quarterly analysis on the prices received from third party pricing services to determine whether the prices are reasonable estimates of fair value, including confirming the fair values of these securities through observable market prices using an alternative pricing source. If differences are noted in this review, the Company may obtain additional information from other pricing services to validate the quoted price. There were no adjustments to prices obtained from third party pricing services as of September 30, 2013 or December 31, 2012 that were material to the consolidated financial statements. If quoted market prices and an estimate determined by using objectively verifiable information are unavailable, the Company produces an estimate of fair value based on internally developed valuation techniques, which, depending on the level of observable market inputs, will render the fair value estimate as Level 2 or Level 3. The Company bases all of its estimates of fair value for assets on the bid price as it represents what a third party market participant would be willing to pay in an arm's length transaction. These methods of valuation will only produce an estimate of fair value if there is objectively verifiable information to produce a valuation. If objectively verifiable information is not available, the Company would be required to produce an estimate of fair value using some of the same methodologies, making assumptions for market-based inputs that are unavailable. Estimates of fair value for fixed maturity securities are based on estimates using objectively verifiable information and are included in the amount disclosed in Level 2 of the hierarchy. The Level 3 fair value estimates include the Company's assumptions about risk assessments and market participant assumptions based on the best information available, including quotes from market makers and other broker/dealers recognized as market participants, using standard or trade derived inputs, new issue data, monthly payment information, cash flow generation, prepayment speeds, spread adjustments, or rating updates. The following table presents the items on the accompanying consolidated balance sheets that are stated at fair value and the fair value measurements.

| Investments | Investments The cost or amortized cost, gross unrealized gains, gross unrealized losses, and estimated fair value of the Company’s investments were as follows:
The amortized cost and estimated fair value of fixed maturity securities at September 30, 2013, by contractual maturity, are shown below. Expected maturities differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.
The following is a summary of investments that have been in a continuous unrealized loss position for less than 12 months and those that have been in a continuous unrealized loss position for 12 months or greater as of September 30, 2013 and December 31, 2012.
Based on reviews of the fixed maturity securities, the Company determined that unrealized losses for the nine months ended September 30, 2013 were primarily the result of changes in prevailing interest rates and not the credit quality of the issuers. The fixed maturity securities whose total fair value was less than amortized cost were not determined to be other-than-temporarily impaired given the severity and duration of the impairment, the credit quality of the issuers, the Company’s intent to not sell the securities, and a determination that it is not more likely than not that the Company will be required to sell the securities until fair value recovers to above cost, or maturity. Based on reviews of the equity securities, the Company recognized an impairment of $0.1 million in the fair value of one equity security for the nine months ended September 30, 2013 as a result of the severity and duration of the change in fair value of that security. Realized gains on investments, net, and the change in unrealized gains (losses) on fixed maturity and equity securities are determined on a specific-identification basis and were as follows:
Net investment income was as follows:
The Company is required by various state laws and regulations to keep securities or letters of credit in depository accounts with certain states in which it does business. As of September 30, 2013 and December 31, 2012, securities having a fair value of $603.4 million and $530.6 million, respectively, were on deposit. These laws and regulations govern not only the amount, but also the types of securities that are eligible for deposit. The deposits are limited to fixed maturity securities in all states. Additionally, certain reinsurance contracts require Company funds to be held in trust for the benefit of the ceding reinsurer to secure the outstanding liabilities assumed by the Company. The fair value of fixed maturity securities held in trust for the benefit of ceding reinsurers at September 30, 2013 and December 31, 2012 was $32.1 million and $35.0 million, respectively. Pursuant to the Amended Credit Facility, a portion of the Company's debt was secured by fixed maturity securities and restricted cash and cash equivalents that had a fair value of $100.6 million and $110.4 million at September 30, 2013 and December 31, 2012, respectively. |

| LPT Agreement [Abstract] | |
| LPT Agreement | LPT Agreement The Company is party to a 100% quota share retroactive reinsurance agreement (LPT Agreement) under which $1.5 billion in liabilities for losses and LAE related to claims incurred by EICN prior to July 1, 1995 were reinsured for consideration of $775.0 million. The LPT Agreement provides coverage up to $2.0 billion. The initial Deferred Gain resulting from the LPT Agreement was recorded as a liability in the accompanying consolidated balance sheets as Deferred reinsurance gain–LPT Agreement. The Company is also entitled to receive a contingent profit commission under the LPT Agreement. The contingent profit commission is an amount based on the favorable difference between actual paid losses and LAE and expected paid losses and LAE as established in the LPT Agreement. The Company records its estimate of contingent profit commission in the accompanying consolidated balance sheets as Contingent commission receivable–LPT Agreement and a corresponding liability is recorded on the accompanying consolidated balance sheets in Deferred reinsurance gain–LPT Agreement. The Deferred Gain is being amortized using the recovery method. Amortization is determined by the proportion of actual reinsurance recoveries to total estimated recoveries over the life of the LPT Agreement, except for the contingent profit commission, which is amortized through June 30, 2024. The amortization is recorded in losses and LAE incurred in the accompanying consolidated statements of comprehensive income. Any adjustments to the Deferred Gain are recorded in losses and LAE incurred in the accompanying consolidated statements of comprehensive income. The Company amortized $22.7 million and $14.0 million of the Deferred Gain for the nine months ended September 30, 2013 and 2012, respectively. Additionally, the Deferred Gain was reduced by $10.1 million in September 2013 due to the favorable LPT Reserve Adjustment (Note 2). The remaining Deferred Gain was $260.6 million and $281.0 million as of September 30, 2013 and December 31, 2012, respectively. The estimated remaining liabilities subject to the LPT Agreement were $633.0 million and $672.3 million as of September 30, 2013 and December 31, 2012, respectively. Losses and LAE paid with respect to the LPT Agreement totaled $630.0 million and $605.1 million through September 30, 2013 and December 31, 2012, respectively. |
