I work from home. It has many advantages, but one big disadvantage is you might not notice it’s a holiday and work anyway.
Dare I ask my boss for Tuesday off since I accidentally worked the holiday anyway?
Ask for time in lieu for the day you worked yesterday. But be aware that it may be a difficult fight for it if no one asked you to work yesterday.
That said, all but the shittiest bosses are likely to approve retroactive time off requests since rejecting them discourages independent working.
Sounds like you’re salaried. Generally those jobs care about getting your work done more than watching a clock or waiting for phones to ring
If you have a decent boss, explaining what happened and asking if you can just take off a different day this coming week would probably be fine, even if Tuesday isn’t feasible on such short notice. Personally, I’d be gunning for Friday (assuming you have the normal weekend days off)
If that conversation is considered a problem, then it’s time to see if the company’s competitors are hiring for your position
