I have a table for job seniority. If a new person is hired, their seniority becomes the next number up from the last seniority number (25, next is 26, etc). If a person leaves the seniority number shifts up in rank and down in number. If I am 25 on the seniority list and someone leaves, my seniority level becomes 24. Can this renumbering be done? Can a form be set up to code so the table is affected correctly. Thank you in advance
I have attached the table.
