Manager expects employee making $75K to take over her late coworker's job, refuses to give her a raise despite the role being worth a $100K salary: 'I’m starting to feel deeply resentful.'

Are they asking her to take on these responsibilities, or are they demanding it?

Taking on more responsibilities at work can be a double-edged sword. Doing so can demonstrate to your boss that you're ready to advance your career and are not afraid of the hard work it takes to move forward. But if you take on more responsibilities without a pay raise or a title bump indefinitely, all you're doing is telling your boss that you're willing to be taken advantage of. It's important to know when to ask for more money or greater official responsibility.

Many employers take their hardworking employees for granted, assuming they will never leave in search of greener pastures. Some employers are willing to work their top-performing employees to the bone until they inevitably leave, to get as much out of them as possible. After all, if you only have to pay $75K for an employee worth $100K, you're getting a pretty sweet deal. Employers either prioritize retaining their talent for as long as possible by keeping them happy, or they're willing to accept higher turnover rates in exchange for lower labor costs. They might prioritize one or the other on a case-by-case basis, depending on how much they value the employee or the position. Still, ultimately, these are the undercurrents of conversations behind closed doors. It's rare for an all-star employee to stay indefinitely at a workplace where they aren't valued.
