Немного подробнее.

Emp# в X__1 будет идти в заголовке первого столбца, который будет иметь значение от X__6 и т. Д.

Учитывая, что ваш формат строго соответствует тому, что вы показываете, может быть еще одна (немного переобученная) идея: 

d1 <- df[c(TRUE, FALSE),]
d2 <- df[c(FALSE, TRUE),]

setNames(data.frame(d1[2], d1[4], d2[2]), c(d1[1,1], d1[1,3], d2[1,1]))

, которая дает

Я добавил новый столбец с именем rid, в котором сгруппированы пары строк, затем отфильтровал необходимые столбцы и left_join() собрал их вместе по их rid. 

library(dplyr)

df <- mutate(df, rid = lapply(1:(nrow(df)/2), function(x) rep(x, 2)) %>% unlist())

left_join(
  df %>%
    filter(X__1 == "Emp #:") %>%
    select(rid, X__6) %>%
    rename("Emp #" = "X__6"),
  df %>%
    filter(X__1 == "Reason of Resignation:") %>%
    select(rid, X__6) %>%
    rename("Reason" = "X__6"),
  by = "rid") %>%
  left_join(df %>%
              filter(X__7 == "Department:") %>%
              select(rid, X__8) %>%
              rename("Department" = "X__8"),
            by = "rid") %>%
  select(-rid)

#  `Emp #` Reason                                                    Department
