I received an informal offer from a software company which included 0 hours of PTO. I countered the offer and was promised 10 days (80 hours) of PTO. With this apparent "signing bonus" as the deciding factor I accepted the offer.
Here is the verbatim verbiage of the contract with regard to PTO:
The following benefits are offered after 30+ days of employment: - (several list items) - up to 9 paid Holidays - 10 days paid vacation/personal time
Several months into the employment I'm now being told, of the 80 hours I was promised, I have only accrued ~28. I understand that accrual of PTO is a common practice, but having received a formal offer of 80 hours (with no stipulations on how that time could be used) I am quite upset and considering suing for breach of contract. HR admitted via email that the only place I could have seen their accrual policy was in the Employee Handbook which they are aware that I did not have access to.
Is this an acceptable business practice?
