The Tudors lost boss Dean Brennan on September 18 but the club are no closer to finding his replacement.
Hemel have released a statement explaining they are happy to bide their time.
Midfielder Parkes, the club captain, will continue to hold the fort in a solo capacity.
“Jordan Parkes will continue to fulfil managerial duties for our upcoming Vanarama National League South match at Truro this Saturday, 13th October 2018, our Herts Senior Cup home tie against Colney Heath on Tuesday 16th October and our FA Cup Fourth Qualifying Round tie against Oxford City, at Vauxhall Road,” read the statement.
“Having previously been appointed as part of a caretaker management team with Jordan, Darren Ward has since decided not to continue in this role. We are grateful to Darren for his work and help during this time.
“In regards to the managerial vacancy created by last month's departure of Dean Brennan and Stuart Maynard, no final decision has yet been made in regards a permanent appointment.
"We expect to make an announcement shortly after Chairman Dave Boggins’ return in two weeks’ time.
“Club officials, staff and players are now focussed on our upcoming fixtures against Truro and Oxford and we encourage the Tudor Army to get behind Jordan and the team as they aim to continue the current run of fantastic form.”
