Should I fire my employee?
Short answer
If you have already had the direct conversation and nothing changed, yes. If you have not, have it this week and decide after.
Run the three questions
Have I told them clearly what is wrong, in plain words, and what good looks like? Did I give them a real chance to fix it, with a deadline? Would I hire them today knowing what I know now?
If the answer to the third is no, you are not firing them. You already did. You just haven't told them yet.
What to do this week
Have a short, calm conversation. Name the behavior, name the impact on the team, and name the timeline to change. Document it the same day in a one-page note.
If nothing changes in two to four weeks, let them go cleanly. Drawn-out firings cost you more in team morale than the employee ever cost you in payroll.
